no logs other than this when running with --verbose - no errors or rendering-related messages. i suspect smth is wrong with the linux impl itself?

i also tried main & could reproduce the issue there too.
maybe related: #182397 (but this by itself didn't fix)
note on other platforms: emoji rendering has worked properly on mac, ios & android with impeller so far for me; only issue is with linux

@f-person Thanks for reporting the issue. Routing this to the engine team for further investigation, as I don’t have a Linux machine to verify it.

fyi @jason-simmons , you might have some ideas here. Maybe the red and blue channels are getting swapped?
